CLARENCE P. FLORA,"OF SOUTH BEND, INDIANA, ASSIGNOR TO SOUTH BEND UNIVERSAL ROLLER WINDOW-SCREEN.

Specification of Letters Patent.

Patented Feb. 9, 1909;

Application filed January 8, 1908 Serial No. 409,851.

To all whom it may concern:

Be it known that I, CLARENCE P. FLORA, a citizen of the United States, residing at South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements inzRoller Window- Screens, of which the followingis a specification.

This invention relates to improvements in rolling window screens of the class wherein a sheet of screen .material is connected at one end to one of the sashes of the window andat the other end to the window frame, and has forits object to improve the construction and increase the efliciency and utility of devices of this character.

With these and other objects in view the invention consists in certain novel features of constructionas hereinafter shown and de'- seribed and specifically pointed out inthe' claims, and in the drawings employed to'illu's trate the preferred embodiment of the invention, Figure 1 is a sectional view of a portion of a window including portions of the frame, the stool or sill, and the u per and lower sash. Fig. 2 is a view of t e lower ortion of the parts shown in Fig. I viewed -rom the outside of the window with the lower sash in closed position. Fig. 3 is'a perspective view of a portion of one of the guide elements. 4 is a longitudinal sectional view of the spring roller employed.

in the improved apparatus. Fig. 5 is a view of the holding wire of the screen sheet.

Fig. 6 is a side view of the binder element of the screen sheet. Fig. 7 is an enlarged end view of the holding wire shown in Fi 5. Fig. 8 is an end view of {one section 0 the spring roller hood. Fig. 9 is a side view of a portion of the hood shown in Fig. 8. Fig. 10 is an end view of the binder element of the screen sheet. Fig. 11 is an enlarged detail view of a portion of the spring roller illustrating the manner in which the screen material is connected thereto.

In the drawings 10 represents the window frame, 11 the outside casing, 12 the inside casing, 13 the outside strip, 14 the inside strip, 15 the partingstrip, 16 the lower memberof the outer sash, 17' the lower member oftheinner sash, 1'8 thesill, and 19. the stool, all t so partsbeingoi theusual construe tion of an ordinary window.

The improved attachment comprises two brackets, one of which is shown at 20 and of a flange which is utilized to receive the holding screws or other fastening means '23 by which the hood and its connecting brackets are attached-to the sash member 17 as; shown. The brackets 20 are designed to support a spring roller represented in detail 1n lug. 4. This roller comprises an outer shell or casing 24 having cup shaped closures 2526. at the ends with flanges 2728 extending therefrom. Intermediate the ends of the shell 24 are blocks 29-3O having central bores 31-32 opposite corresponding apertures in the closures 25-26, and extending slidably through the block bores and the closure apertures are rods 3334, the outer ends oi the rods being flattened or otherwise of irregular shape andadapted to ans flat-asset t as: ets 20, one of tliese apertures being shown at 34 in Fig. 8, so that the rods are held from rotation, while the shell 24 is free to be oscillated around the rods. A spring 35 is connected at one end at 36 to the rod 33 and with its other end extending through the block 29, as shown at 37, while a spring 38 is likewise arranged relative to the rod 34, with one end connected to the rod 39 and the other end extending through the block 30, as shown at 40. By this arrangement it will be obvious that a simply constructed and easily actuated and efficient spring roller is produced.

The shell 24 is formed by bending a sheet of metal into a tube with the edges turned III?- w'ardly, and between which the end of the screen material indicated at 41 is inserted,

and the inturned edges of the shell with the screen material between them rolled together, as indicated at 42 in Fig. 11, thereby firmly securing theu per edge of the screen ma terial to the rol er.

The lower edge of the screen material 41 is provided with a suitable binding element formed from a sin le strip of sheet metal folded 11 on itself and between the sides 43-44 of wiich the lower edge of the screen material is disposed, and the folded strip again bent intermediate its side edges, as shown at 45 in Fi 10 with thebight portion tubularl orm, the intermediate part of the tubular ortions.4647..bein cut away as shown at 48in Fig; 6. The tu 46-47 are utilized to support a holding deular portions.

' stops 13 are L-shaped metal strips 55 with one web of each extending inwardly and with an offset near the lower endsof the inwardly projecting webs, one of these offsets being shown at 56, the lower edges of the offsets being s aced from the sill 18. The hood 21 is notciied at its ends where its outer portion crosses the inwardly extending webs of the members 55, as indicated at 57 in Fig. 9, so that as the sash member 17 is raised and lowered the hood 21 will be guided by the inwardly extending webs of the members 55. By this arrangement the lower edge of the screen material is readily and quickly connected in place by inserting the binder members 43-44 against the lower ortions of the inwardly extending webs of t e ortions 55 with the outer ends of the tub ar portions 4647 beneath the offsets 56 and with, the

pointed terminals 54 of the ends 52-53 of the holding wire engaging against the outer face of the parting strip 15, as represented in Fig. 1, the resiliency 0 he holding rod being thus utilized to firmly connect the lower edge of the screen material to the sill,-while at the'same time enablin the screen material to be readily detached ysimplyreleaswinnfi the ends 52-53 of' the holding w re, as be obvious.

By this simple arrangement'it will be obvious that a very simply constructed, easily applied, and inexpensive rolling screen is produced, which Wlll be, automatically wound up by the spring roller when the inner sash is closed, or disposed in the position shown in Fig. 2, .and will unroll automatically as the inner sash is opened, and thus form an efiicient screencove ingthe opening in the window formed by raising the inner sash.

The hood 21 is formed in two portions with their adjacent ends 'overla ping as shown in Fig. 2, so that the'hoo may be readily adapted to windows of varying widths.

Having thus described the invention, what is claimed as new is 1 In a device of the class described, a.

roller adapted tobe connected to a window sash, screen material connected-at one edge to said roller, a binding element connected to the opposite edge of said screen material, stops adapted to be connected to a window frame, an element connected for oscillation to said binding element and having portions bearing portions to engage said stops to hold one edge of the screen material against displacement, and also having an offset portion for engagement with a window sill.
